Both an IUL and a Roth IRA can produce tax-free retirement income — which is why agents love comparing them and why the comparisons you find online are usually one-sided. Here's the answer I give my own clients, even though I sell IULs:
Fill the Roth first. Then, if you've hit its limits — either the contribution cap or the income phase-out — the IUL becomes one of the best remaining tax-advantaged buckets available. Let me show you exactly why, with 2026 numbers.
The 2026 Roth IRA Reality Check
Per the IRS, for 2026:
- Contribution limit: $7,500 (plus a $1,100 catch-up if you're 50+, for $8,600 total)
- Income phase-out: $153,000–$168,000 (single) and $242,000–$252,000 (married filing jointly). Above the top of the range, direct Roth contributions are off the table.
Those two numbers define this whole debate. If you earn $120k and save $500/month, the Roth handles most of it and this comparison barely matters. If you earn $300k and want to put away $3,000/month tax-advantaged, the Roth can't hold it — and that's where the IUL enters.
Head-to-Head
| Roth IRA | IUL | |
|---|---|---|
| 2026 contribution limit | $7,500 / $8,600 | MEC limit — commonly $20k–$100k+/yr by design |
| Income restrictions | Phases out at $153k–$168k single | None |
| Growth | Uncapped market returns | Index-credited: 0% floor, capped/participation-limited upside |
| Costs | Fund expenses only (can be near-zero) | Cost of insurance + policy fees |
| Tax-free access | Contributions anytime; earnings after 59½ + 5 years | Basis withdrawals + policy loans anytime, if policy stays in force |
| Market risk | Full downside exposure | 0% floor on crediting |
| Death benefit | Account balance only | Income-tax-free death benefit from day one |
| Risk of failure | None (it's just an account) | Lapse risk if underfunded or loans unmanaged |
Why the Roth Wins Round One
For the first $7,500/year, the Roth IRA is nearly unbeatable:
- No insurance costs. Every dollar compounds; nothing goes to cost-of-insurance charges.
- Uncapped growth. A low-cost index fund captures the full market return, not a capped slice.
- Simplicity and zero failure modes. A Roth can't lapse.
Any agent who tells you to skip an available Roth to fund an IUL instead is prioritizing their commission over your outcome. Full stop.

The IUL's case begins where the Roth's ends:
- No income limits and no meaningful contribution cap. A high earner locked out of direct Roth contributions can fund an IUL at $2,000, $5,000, or $10,000/month. (Yes, backdoor Roths exist — but they're still capped at $7,500.)
- Downside protection. The 0% crediting floor eliminates sequence-of-returns risk on that bucket — a crash the year before retirement doesn't touch prior credits.
- Liquidity before 59½. Roth earnings are locked until 59½; IUL cash value is accessible at any age through basis withdrawals and loans.
- A self-completing plan. The death benefit means the plan delivers for your family even if you die in year three. And living benefit riders can pay out for chronic or critical illness.
- Loans don't hit your tax return. IUL loan income doesn't raise provisional income for Social Security taxation or Medicare IRMAA brackets — same practical result as Roth withdrawals, without the contribution ceiling.
The Honest Costs of Choosing the IUL
- Insurance drag. Cost-of-insurance and policy charges mean an IUL must be max-funded (minimum death benefit for the premium) to compete. Casually funded IULs lose to almost everything.
- Capped upside. In a decade like the 2010s, an uncapped index fund beats capped crediting. The IUL trades peak returns for floor protection — know that you're making that trade.
- Commitment. A Roth tolerates skipped years gracefully. An IUL is designed around consistent funding for 10–20 years.

For most of my clients, the order looks like this:
- 401(k) up to the full employer match
- Roth IRA to the max — directly, or via backdoor if income-phased-out
- HSA if eligible (triple tax advantage)
- Max-funded IUL for tax-free capacity beyond all of the above — especially for earners above ~$168k single / ~$252k married who want six figures a year going into tax-advantaged buckets
- Taxable brokerage for everything else

FAQ
Can I have both an IUL and a Roth IRA? Yes, and for high earners that's usually the right answer — they're complementary tax-free buckets, not competitors.
Is an IUL better than a Roth IRA for high income earners? Above the Roth phase-out ($168k single / $252k married in 2026), the direct Roth isn't available at all — the practical comparison becomes IUL vs backdoor Roth vs taxable investing, and the IUL's unlimited funding capacity is its main edge.
Does an IUL have RMDs like a traditional IRA? No. Neither Roth IRAs nor IULs force required minimum distributions during the owner's lifetime.
Which has better returns, IUL or Roth IRA? The investments inside a Roth typically out-return IUL crediting over long periods because they're uncapped. The IUL competes on tax capacity, downside protection, and the death benefit — not raw return.
